BBA Refurb hasn't worked - Help!

[Andypa]

Help, I'm stuck!!

Finally got my ETM back from BBA today after being car less for nearly 3 weeks because they had run out of spare parts, but didn't bother to tell me that when I booked the job with them (more details in the "Is this ETM fault" and "ETM - Refurb by Autotek" threads)

Bear in mind that they bench tested the unit and confirmed that it needed new sensors, guess what......IT DOESN'T WORK!!!!!

No instructions came back with the part, but I had read somewhere on here that after fitting it back onto the car, it needs to be left for a few minutes with the ignition on before turning the engine over to allow the cars ECU to recognise the new parts. So I did leave it for around 20 minutes first. It made a high pitch whine for the first few minutes, which went off when I turned the ignition off and now only comes on for several seconds each time the ignition is turned on (although to be fair you can't hear this with the engine running, so it may always have done this, I don't know)

The warning messages already stored on the display didn't go off in this time (or since), these were "Engine system service" and "Engine system service urgent". But when I fired it up, it started ok and ran for about 3 miles to the local supermarket. But when I started it up after coming out of the supermarket, the revs started climbing and it went into limp home mode and I've also now got another warning message "reduced performance".

Unfortunatley, I have switched the engine off and on dozens of times in between driving around in it, but I can't clear it. I could generally clear it by doing this before, so it's probably worse now than before!

I'm dreading phoning BBA tommorow, the woman who seems to be in charge of customer relations seems to get easily offended if there is even a hint that you may be being critical or asking a question that she doesn't know the answer to. In her own words "I'm just trying to be a good go-between between you and purchase". She was pretty curt this morning when I rang to check that the part was definitely on it's way back to me. Bear in mind that there was a c**k up on collection and it was a day late and this morning their online parts tracker only gave a link to the inbound shipping details from 3 weeks ago. I'm going to try extra hard to curb my frustration and be extra friendly, but I need to have a contructive conversation with someone who is technically clued up..............wish me luck!

ps I noticed that the new plastic cap that contains the sensor has been freshly ground away on it's outermost face. I don't know the relevance of this or if anyone else had the same. The only thing that I could think of was that it was to hide a manufacturer's logo?

From my experience, I really can't recommend using BBA, to date it would have been cheaper to go to a main dealer, and I still haven't resolved it yet
