We were around 30 miles away from France when we were asked to look at a Golf MK4 in Folkestone, Kent, which was having issues starting.

The owner happened to conincidentally have these issues after trial fitting some new instrument clusters to his car

After some initial investigation, we pin pointed the issue to the engine ECU.

After stripping the scuttle panel and removing the wipers, we could see that the ECU had visible signs of water ingress within the wiring harness.

The ECU had been damaged with one of the pins being corroded and also the engine harness required replacing

After the owner replaced both parts, we paid another visit to plug it all together and program the ECU / instrument clusters

Proof that sometimes, an enthusiast with a VAGCOM / VCDS cable is simply not enough!

Another happy customer!
