Now carrying the post mapping smile... what a difference! Smoother tick over, faster delivery.... it’s like a different engine. Thank you Mike. Off for another drive now.....

Waiting to leave work early to meet Dynachip Mike, who is turning up this afternoon to drain the “1’s” and “0’s” out of my ECU and top up with fresh code

Replied to wrong thread ..... please ignore!

Re the ACE light.... mine occasionally came on after some “spirited” on-road driving... Amber (not red with chimes). Having checked for leaks etc, I took a punt on the pressure transducer on the block under the drivers side (this being a popular culprit) and I don’t have access to read...

Duly noted, thank you! Ignorant question, but would the TC shudder be evident if it was locked? As I say, it was that happy place where the TC was locked, and rolling along at around the speed limit with 2500ish rpm showing... I tried to avoid a throttle position that disengaged the lock...

@sierrafery, actually couldn't say with any confidence re the oil - but good call, thank you. May be worth doing a bit of a swap / freshen-up, it's only the cost of the oil....

Hi all, quick question to see if I can narrow down an issue.... Td5 auto, 90K on clock. Runs well, no problems starting, good clean power upon pulling away etc. On weekend, travelling back to London along the M20, happily rolling along and keeping up with the traffic around 70mph ish... no...

Swapped out the pressure transducer on the ACE block, super drive back from Somerset to London... no “wobbly handling” light......

Forgot my other problem... ACE light (amber) so have taken a punt on new pressure transducer and lots of : 1) cleanliness 2) speed 3) 27mm long reach sockets 4) a decent kerb so I can get to it!

Pelican = Big Bill......

Cheers Neilly... hopefully it will defer the replacement PAS box for a month or two...

Little bit of context.... Coolant leaking into drivers footwell (heater matrix.. dash out... ) Pelican Over pressure in cooling system (despite heater matrix....) Pleican Unresolved engine oil leak .... definite Pelican

This stuff....

Now I fell a telling-off about to happen... Lucas Oil....

Could not face the £600 plus bill for a new PAS box and added Snakeoil to the resovoir.... leaking stopped, at least until I can get my next invoice paid.....

Good call, thanks...

Thank you all... so key messages; keep it clean and move fast!

Hi all, quick question if I may, subject to a code read, I believe the transducer may be the cause of my amber ACE light (no fluid loss etc). If I replace the transducer myself, is there any subsequent setting needed from a reader, or is it just a plug and play? Thanks in advance!

@brian47 - surely this is the kind of place that you can admit it was your own glitter...:)

@Paul D - I have some works on the centre console planned - so will be removing part, so on that basis I'll carry on until I can see the movement you describe... then liberal application of grease!
