Thankyou and just from googling the problem it seemed to be the next thing to try after a change of coils. RHi Rachel
The ECU is under the passenger floor. Lift up the front carpet and there is a metal panel with 3 twist clips. The ECU and CCCU are under there in a black plastic cradle.
Can I ask what leads you to believe that you need to clean your ECU? It is an electrical component stored in a clean dry oart of the car.
Welcome from me too!Thanks for the warm welcome ? it started with an occasional loss of power. Now the engine light is on and there is a constant loss of power particularly acceleration. When the engine light starts flashing she judders and jolts and it's like driving a tractor! R
Assuming that the A2 with the issue is the same A2 that’s listed on Rachel’s profile, it’s a 1.4 MPI.Maybe I missed it, what engine is your A2 please, I'm guessing it might be a 1.6 FSI?
It's a 1.4 petrol sport ?Welcome from me too!

Thanks for that funnily enough having the same issues with earthing out with my 924 ? RYou could ask here what you asked Google.
Have you scanned it with VCDS? If you're in this for the long term, buy a cable for it. All cars made this century first thing to do is to talk to it and let it tell you what it's not happy about.
Second is, have you checked the earth cable, this is the second of two most common things suggested. In the same way the ECU will tell you what's wrong, all the stuff it talks too needs a good ground and a decent voltage coming from the battery so they don't grumble to the ECU saying 'implausible signal' and voltage 'out of range'. My A2 and TT grumble less once I'd sorted a new battery (and alternator for the A2) and a new earth cable.
TBH, I think your 'new member' to 'member' forum status only changes when someone has replied with 'Scan with VCDS' and 'Check the earth'
Um where would I find the earth cable....Thanks for that funnily enough having the same issues with earthing out with my 924 ? R
Behind the nearside headlight, which you need to remove (2 bolts, one connector). Long extension required to get to the bolt head along the chassis leg and under the AC pipes if you have AC. Clean up the mating faces to bare metal. The earth strap has also been known to look OK from the outside but be corroded right through inside its plastic coating, so once disconnected give it a good tug to check if you need a new one.Um where would I find the earth cable....

Thankyou and fingers crossed! She is so easy to drive I would hate to give up ?Welcome to the forum.
I had similar driving issues with my Fsi, replaced the rusty washer behind the passenger headlight eart cable & problem solved.
It’s always worth asking the question, I think. Plenty of people have multiple A2s, or have sold one and bought another without updating their A2OC profile. Confirmation can never harm.? Dooh

Sounds to me like a misfire, running on less than 4 cylinders - this is the exact symptom we had with ours. From experience, I would bet on needing a replacement coil, and depending on how well maintained the rest of the engine is, possibly plugs and leads could help as well.Thanks for the warm welcome ? it started with an occasional loss of power.

Unlikley to be the wiper motor thats at fault, run a cable from a bolt on the motor to a bolt on the chassis. You will probably find this solves it and is likely to just be a bad earth on the wiper motor again.She now needs a new wiper unit where should we try?
Thanks!
