Warranty Policy

Unless a product page or individual warranty statement provides more favourable terms, the following commercial-warranty periods apply from delivery of a shipped Product or handover of a vehicle after workshop repair:

• Products shipped to the customer, including torque converters: 6 months
• Products shipped to the customer, including valve bodies, mechatronics and electronic components expressly covered on the product page: 6 months
• Products shipped to the customer, including complete automatic transmissions: 6 months; repairs performed at MID Auto’s Varna facility on a vehicle delivered to us: 12 months on the performed repair

A Product category is covered only if the product page, order confirmation, invoice or warranty statement says so. The guarantor is the Seller identified on those documents and the commercial warranty applies in the delivery country unless expressly limited before purchase.

The following conditions apply to the additional commercial warranty. They do not reduce mandatory Consumer rights under the legal guarantee of conformity.

Installation must be performed by MID Auto or a qualified technician/professional workshop with relevant transmission experience, following the vehicle and component manufacturer’s procedures.

For a commercial-warranty claim, MID Auto may request proportionate proof such as:

• workshop invoice or service receipt
• workshop details
• technician name
• written confirmation of the installation work performed

Where applicable, programming, coding, calibration, adaptation/relearn and pre-/post-installation diagnostics must be completed correctly and retained in the service record.

This may include:

• programming records
• adaptation or relearn procedures
• pre-installation and post-installation diagnostic scans
• fault codes and diagnostic reports
• evidence of software-related procedures carried out during installation

The exact ATF specification, quantity and filling procedure prescribed for the vehicle/transmission must be used, together with required filters, seals, cooler flushing or replacement and related service materials.

Supporting evidence may include:

• invoice for purchased ATF
• specification of the fluid used
• proof of quantity filled
• invoices for filters, seals, gaskets, or other related service parts where relevant

The vehicle, cooler, lines, electrical supply, software, engine and related transmission systems must be inspected and maintained so that an external condition does not cause or contribute to failure.

This may include records relating to:

• fluid service history
• cooling system condition
• related repairs
• diagnostic history
• previous gearbox or valve body issues
• contamination from prior component failure

The commercial warranty covers a defect in materials or workmanship confirmed to have arisen under normal intended use during the applicable period. Coverage is limited to the Product or repair expressly identified in the warranty statement.

For an accepted commercial-warranty claim, the guarantor may choose a proportionate remedy:

• repair the Product or repeated workshop work
• replace it with an equivalent new or remanufactured Product
• refund up to the original price paid for the affected Product or repair where repair/replacement is unavailable or disproportionate

The remedy depends on technical findings, feasibility, stock and proportionality. Consumer statutory remedies, their order and the right to price reduction or termination are determined separately by mandatory law and remain free of charge.

The commercial warranty does not cover loss or damage to the extent caused or materially contributed to by:

• incorrect installation or failure to follow mandatory installation instructions
• installation by a person lacking the competence required for the work, where this caused or prevented reliable diagnosis of the failure
• incorrect programming, coding, calibration, adaptation or software configuration
• incorrect, insufficient, contaminated, overheated or degraded ATF
• failure to flush/replace a contaminated cooler, lines, filter or related component where required
• debris or contamination from a prior or external system failure
• overheating or inadequate cooling
• misuse, overload, abnormal use or operation contrary to instructions
• racing, competition, tuning beyond specification or severe operating abuse
• impact, water ingress, fire, electrical overvoltage or other external damage
• transport damage occurring after risk passed to the customer, unless attributable to the Seller/carrier under applicable law
• improper storage, corrosion or inadequate packaging after delivery
• unauthorised disassembly, tampering or modification where it caused the failure or materially prevents reliable technical evaluation
• continued operation after warning symptoms or a fault became apparent, to the extent this worsened the damage
• a fault originating in another vehicle, electrical, hydraulic, software or cooling system
• labour and workshop charges not expressly authorised in writing under the commercial warranty
• vehicle downtime or loss of use under B2B/commercial claims
• towing, recovery or substitute transport not expressly authorised
• loss of income, profit, customers or business opportunity for B2B Customers
• additional diagnostics, removal, reinstallation or workshop work not expressly authorised
• indirect or consequential damage, subject always to liability that cannot lawfully be excluded and to mandatory Consumer rights

For the commercial warranty, submit the official Claim Form with reasonably available information. A statutory Consumer complaint may be submitted in any clear form and will be registered even if commercial-warranty documentation is incomplete.

Submit a claim: Submit a claim

Before sending a Product, contact MID Auto so that the Seller can preserve evidence, give safe packaging/transport instructions and decide whether remote diagnostics or return inspection is required.

The form requires, among other things:

• customer and order details
• product identification
• installation and workshop information
• vehicle details
• description of the issue
• diagnostic information
• supporting documents

Submission registers the matter but does not predetermine whether the cause falls under statutory non-conformity, commercial warranty or an excluded external condition.

MID Auto conducts an initial review, preserves the original receipt date and may request proportionate additional information.

Where return inspection is required, MID Auto issues an RMA number and instructions. For a commercial-warranty/B2B claim, return without RMA may be refused for safety and traceability reasons.

A missing RMA does not, by itself, invalidate a Consumer statutory complaint, but the Consumer must cooperate with reasonable identification, collection and inspection arrangements.

Depending on the Product and reported symptom, relevant evidence may include:

• proof of purchase
• professional-installation details or proof, particularly for the commercial warranty
• workshop invoice or service documentation
• diagnostic reports
• OBD fault codes
• programming and adaptation records
• photos and/or videos showing the issue
• ATF invoices and fluid specification details
• maintenance records relevant to the transmission system

Missing evidence may delay or prevent acceptance under the commercial warranty where MID Auto cannot verify compliance or causation. It is not an automatic reason to reject a statutory Consumer claim if the facts can be established otherwise.

If reasonably necessary, the Product must be made available or returned for technical inspection. The customer must stop use where continued operation could cause further damage and preserve fluids, removed parts, fault codes and other relevant evidence where practical.

The Product must be drained where instructed and packed for its weight and protruding parts using the original or equivalent protective packaging. The sender is responsible for avoidable return damage caused by inadequate packaging.

Mark the issued RMA on the package and use the specified return address/carrier instructions.

Returned Products are logged by RMA, order, serial number, seal condition, photographs, weight and condition on receipt. MID Auto maintains a technical inspection record proportionate to the claim.

Inspection may include:

• visual examination
• disassembly
• measurement
• controlled testing
• review of installation and diagnostic records

The outcome is based on documented observations, measurements, controlled tests, fault data and the probable causal link. MID Auto may use an external specialist where appropriate; no party is bound by an unsupported “sole judgment”.

No final commercial-warranty remedy is selected before the necessary inspection is complete. For Consumer statutory claims, inspection and the remedy are completed within mandatory deadlines and without significant inconvenience.

For a commercial-warranty or B2B inspection, the customer normally arranges and initially pays return transport unless MID Auto provides another method. For a Consumer statutory non-conformity claim, necessary postage, transport, labour and materials are borne by the Seller where required by law.

If a commercial-warranty claim is accepted, MID Auto reimburses reasonable pre-approved standard return shipping or provides equivalent transport support. Premium, unauthorised or incorrectly routed transport is not reimbursed.

Customs, duties, diagnostics, removal, reinstallation, recovery and third-party expenses are covered only where mandatory Consumer law requires or MID Auto expressly approved them in writing in advance.

A claim may be rejected where the documented evidence shows that the failure is outside the applicable commercial warranty or arose after delivery from an excluded cause. A Consumer statutory claim is decided under the applicable burden-of-proof rules and cannot be rejected solely by referring to a commercial-warranty exclusion.

In such cases:

• no free commercial-warranty repair, replacement or refund is due
• for B2B/commercial claims, the customer may be charged the reasonable pre-disclosed inspection, storage and return-shipping cost
• MID Auto provides a reasoned outcome and an inspection summary sufficient to explain the decision; proprietary test methods and third-party confidential data need not be disclosed

For Consumers, nothing in this section limits mandatory remedies, product liability, death/personal-injury liability, or liability for wilful misconduct or gross negligence. The limitations below govern only the additional commercial warranty and B2B claims to the extent lawful.

For B2B Customers, MID Auto is not liable under the commercial warranty for indirect, incidental, punitive or consequential loss, including:

• labor costs
• reinstallation costs
• removal costs
• diagnostic time
• transport costs
• towing
• vehicle downtime
• rental vehicle expenses
• missed business opportunities
• additional repair costs not expressly authorised; aggregate liability is limited to the price paid for the affected Product or repair, subject to non-excludable law

For international claims, use the RMA and customs instructions supplied by the Seller. Cost allocation follows section 7 and mandatory Consumer law; the customer is responsible for loss, delay and charges caused by inaccurate declarations or unauthorised routing.

Cross-border transport and customs may affect factual inspection timing, but do not extend mandatory Consumer remedy periods beyond applicable law.

MID Auto aims to acknowledge and initially review a complete claim within 7 working days. This is a service target and does not replace statutory periods.

The customer may receive:

• an RMA number and return instructions, or
• a request for additional information or documents

Technical evaluation takes a reasonable period proportionate to the Product and fault. Consumer statutory cases are completed within the mandatory deadline and without significant inconvenience; complex B2B/commercial cases receive material status updates.

The customer must provide reasonable cooperation and must not authorise third-party dismantling or destructive work after claim notice without preserving evidence or obtaining MID Auto’s written instructions, except where urgently necessary to prevent further damage or ensure safety.

The commercial warranty is for the original purchaser and is transferable only with MID Auto’s written agreement. This does not restrict any statutory right that applicable law grants to a Consumer or successor.

A commercial-warranty claim may be refused where:

• requested documents reasonably necessary to prove commercial-warranty compliance remain materially incomplete after a fair opportunity to provide them
• handling, storage, installation or operation caused or materially contributed to the failure
• alteration, disassembly or damage caused the issue or prevents reliable evaluation
• the commercial-warranty period expired before the defect was reported
• the evidence does not establish a covered materials/workmanship defect; this sentence does not reverse any statutory Consumer presumption

MID Auto may amend this Policy prospectively. The version supplied on a durable medium and in force at purchase applies to the order, subject to later mandatory law more favourable to a Consumer.

The commercial warranty in this document is additional to the legal guarantee of conformity and does not replace it.

For sales by a Bulgarian Seller, the Seller is liable for qualifying non-conformity appearing within at least two years after delivery; more favourable mandatory law in the Consumer’s country may apply.

• Statutory remedies are free of charge and are governed by law, including the applicable burden-of-proof rules.
• Professional-installation and document requirements are conditions of this commercial warranty, but missing paperwork alone does not automatically defeat a statutory Consumer complaint.
• A Consumer may complain by any clear statement; the online form and RMA are recommended for traceability but are not mandatory for validity.
• The guarantor is the Seller named in the order confirmation, invoice and any individual guarantee statement.
• Where mandatory law extends the liability period because the Consumer chooses repair, that extension applies automatically.
