Just thought id post this up. Theres a place the other side of Southend that do ECU repair, diagnostic and replacments.
Needed my ECU replaced, called these guys, during last week, popped down Saturday morning (yesterday) and 2 hours later all done and car is driving like a dream!
Really nice guys.
Company is Automotive ECU - www.automotiveecu.co.uk
To supply, fit and program a brand new ECU (with 12 months warranty) £275 + VAT (X18XE1 ECU)
Def worth giving them a call if you need this king of problem sorted
