Title: Double boost?
Post by: Nino on 07 March 2013, 14:53

Gunna scan her later and I suspect I still go that stupid 17005 thingy but the last day or two I have noticed that if I floor it abit she boosts up to about 8-10 psi, drops to 5ish then goes goes back up then hold steady at 5-6?

I have had that error code for a year and changed many things but she's never "double boosted" before. Any ideas?

Would a damaged N75 or damaged N249 cause this?

duff N75 could cause erratic boosting or MAF sensor and not show up any fault codes

£40 for a N75 from the dealers and a five minute job to replace

I thought 17705 was a bug in the standard ecu?
