Hello again. I am afraid I am back as the problem with car going into limp mode persists.
My son tried two independent VW specialists. After looking at the ODIS report, one refused to get involved, saying it could be anything!
Other had a look, and came to same conclusions as me!
Problem is almost certainly loosing the 5V reference for sensors. All sensors connected have been replaced (with a mix of new and used parts) and fault remains.
wiring loom has been inspected, and no issues found.
So this leads to a possible ECU fault.
I have seen an ECU set on eBay for £250 eBay ECU, so want to try swapping this out (If it doesn't work I can re-sell and get money back).
What exactly is involved with an ECU swap?
What do I need to look out for with a used ECU. What part numbers are critical?
If I go back to original will the mileage be affected.
Anyone done this job and give some insight as to how difficult it is.
Mainly just want to diagnose if fault is in ECU or not.
Thanks
