Highly recommend!! Sent an airbag module in to be repaired as mine had stopped working on my Abarth. Had a phone call to … More let me know mine was completely toast and needed to get another to have my data sent over. Sent me all photos of mine, and constant updates to let me know that they were successful doing it! Considering I had to send two they were also super quick fixing and sending back. Also had a refund for the original service I paid for. Would definitely recommend to others and come back in the future if need be. Thank you so much again!

Thank you so much for your help transferring the data from old corrupt ecu to another working unit. Also for your honesty … More & professionalism is advising us that our immobiliser could not be turned off on our particular ecu, which various other companies claimed could be, resulting in us being off the road for some time until we fortunately found you! Turn around time was light speed! Absolutely 5 stars all round!

Excellent service from J C Cars.

The service was very quick. I refitted the airbag ECU to my Fiat 500 and started the vehicle. Most of the warning lights … More that had come on previously were now off, except the airbag light. A call to Justin confirmed that the car needed to have any error codes removed. A job for my local garage. The error codes were removed and the airbag light is now off. All fixed and back to normal. Thanks. The hardest part was removing the unit, even with the excellent video instruction. Who designs cars like this? I found using an electric ratchet with a 10mm socket worked the best, while lying on the pavement with the passenger door wide open.

Important! – Please read! - Please research before ordering whether or not this component will need programming to your vehicle - if so we do NOT offer a programming service for this component by post - It is essential before ordering an item that the part number of the item you are ordering matches the part number EXACTLY of the component on your car that you need to replace. Also ensure that the fault with your car is an ECU fault and your problem has not been misdiagnosed. We strongly recommend having your car diagnosed by a competent Auto-electrician or specialist garage before ordering. If we supply a faulty ECU we are happy to provide a replacement or fully refund you if a replacement is unavailable, however if your existing problem persists with your car then the fault has most probably been misdiagnosed – if you request a refund on this basis then a 20% restocking fee will be deducted from your refund & return postage will be at purchasers expense.

Scan the vehicle with a diagnostic scanner

1 . Scan the vehicle with a diagnostic scanner & record fault codes – rectify any faults recorded here first & check the wiring for faults

If your ECU has ‘No communication’

2 – If your ECU has ‘No communication’ with a diagnostic scanner it is essential that you check relevant fuses and consult a wiring diagram for your vehicle and verify the power supply & test the wiring to your ECU – particularly test power supply relays (Engine control relay). – ECU’s returned due to misdiagnosis are subject to a 20% restocking charge

If you are not a qualified auto electrician

If you are not a qualified / experienced auto electrician or garage technician and you are unsure if the problem with your car is the ECU then please consult one first before ordering – there is a 20% restocking charge for returns due to misdiagnosis

If your fault is a cylinder misfire

If your fault is a cylinder misfire please check spark plugs / leads / coil / injectors and wiring faults / headgasket faults etc before ordering, if these have been checked or replaced then it is important to check inlet manifolds for leaks, engine compression & perform a vacuum gauge test to check for valve problems.
