Hi Aidan.
"If you do go down repair rout avoid external repair that was offered by some suppliers, this looks like a bodge and in my opinion not an acceptable repair"

I assume this is in reference to early BBA remaned unit. Yes it was a ugly repair but worked fine.
They are now internal repair (135 sterling + vat)

Dealer repair kit price seems to go up weekly and was about 280+vat about 2 weeks ago about 100 pound increase in 3 months (they have to get some money back on those free injectors) .

Geoff the choice is yours!

As an aside had one with the same system on a Susuki last week and new unit complete only 1366 pounds +vat eeerr went remaned unit

Regards
Kev.
