Well, I refused to replace with a new ECU . I suggested a eBay ECU and he said he will try to fit it but he will not be responsible for the outcome. And that's what he's done , replaced. With no coding involved , unsuccessful. And charged for trying.
The SKC of both the 'new' and 'old' ECUs is always required when performing a replacement unless the immobiliser of the 'new' ECU has been deliberately disabled. I've chatted to @NoobTech a little via PM. I think it's fairly clear that his A2 has, unfortunately, found its way to a garage who are, at best, totally out of their depth. I'm seriously doubtful that their diagnosis of a faulty ECU is even correct.
Hi Tom,
That's what he says, I asked for all the replaced parts to be handled to me. But can't be sure if it's my part or if he didn't tampered with ...
I don't like finger pointing until I'm sure of my "investigation" .
Very true , I did try to find someone local and possibly from the forum but difficult to find ... I was hoping to be a quick fix as car is a new acquisition .
Don't know really what the mechanic checked , but obviously he "did everything he could" ...
So the bill for £800 is for a failed attempt at replacing the ECU? This is half an hour's work at most!
In that case you need legal advice, especially as the original quotation included a new ECU, which he hasn't provided and would have covered most of the £800. Frankly, he shouldn't be charging you anything for his failure. Have you contacted Trading Standards or Citizens Advice? They are both free. You also need to think about a "review" on Facebook!
