Two companies come up as repairing TD5 ECU's
Alive, and Empire Tuning
l got through to Alive and the guy was really helpful, they may be able to repair it but need to see the unit, if it can't be repaired they can transfer the software over to a replacement and that costs £1,000
lf it can be repaired it's around £200
There's a company near me who sell replacement second hand TD5 ECU's for £700 and it might have to be that, to get the vehicle back on the road, and send mine to Alive to see if it can be repaired as a spare.
