Due to me leaving my lights on, the battery went flat. I recharged it no problem. However I inadvertently connected the terminal the wrong way round and buggered up the electronics. I soon realized my mistake and rectified the problem. All seemed okay until the automatic gearbox began acting erratically by staying in 2nd, also the airbag light stayed on and after starting the car; a clicking noise came from the dashboard. A local garage thinks that the ECU might be burnt out and that a VW dealer will have to rectify the problem. Can you offer any cheaper alternatives please?
Collected car yesterday from VW main dealer. They had rectified most faults, ie airbag light, clicking noise after start up, the automatic working through the ratio's of 1st, 2nd, & 3rd. However after a drive I discovered that the car will not change into 4th. I returned it to VW and they said they were never told about this fault by the original garage I took it to, and that were only asked to get the car started. I queried that their mechanic should have noticed this fault on his test drive. They disagreed as they only took it a short drive. They hooked it up to some gizmo and say that there is a fault with the automatic transmission
The VW garage as now replied and say the problem is the auto box valve(?), which needs to be replaced and will correct the problem with 3rd gear. The total cost of this will be £848.95 which includes parts and labour. I don't know if this is related to the original problem I caused with the battery or a possible fault with the ECU. I have asked for a breakdown of costs. As I'm not entiely convinced with the diagnosis and they may have opted for the more expensive option. Any ideas please?
