T5 idle issues solved!!

[t5 stealth]

i only ever use tesco momentum stuff,
never had a problem with it,ever

have you got a P2 T5..???


if so this leads me to think there's still probably something wrong with mine......

[vaderboyo]

the only reason i buy tesco fuel is cos of the club card points......saving enough ponits to get free RAC cover for when their petrol knackers my engine lol

no but the engine aint much different lol.
i hope you have cured it tho

I got out off the tesco petrol before when they had tesco super unleaded i had a burnt valve and quite a few others around the same time and then funnly enough the tesco super was took off and moved to the momentrum stuff weather is was coinsidence i dont know but have only ever used shell since with no problems what so ever and all the same mods and map

Tesco got screwed a while back for selling dodgy fuel that knackered a lot of engines...

[JamesT5]

yep, crap fuel is crap!!!


coils did cross my mind as did the ETM...... ive got the later Bosch ETM on mine & ive heard when these go they just go.. no throttle flutter.

the coils would of been looked at next, but ...... not a Tesco is sight & all is well!

No, from what I understood the fuel you were using was premium fuel like V-Power and you said it has mucked your engine up. I've used Supermarket fuel with no issues and I get loyalty points too.

yeah it was destroying lambda sensors,i think it cost tesco a few quid that mistake lol

I know a tesco near my the tanker driver mixed up the diesel & petrol tanks when he did a delivery,that did cost them a bit I think it was 20-30 cars until they were told they had a problem.

Yes mate, it's a P2.

[M-R-P]

It could be just a bad batch from a particular Tesco?

They don't all come off the same ship.

[LeeT5]

Funny, i never realised Tesco made fuel!???

Anyway, from what i know, petrol all comes from the same refinery. It's the additives they put in b4 it fills the tankers which denotes, Tesco MOmentum, Esso, Shell V-power, etc etc. Obviously BP use their own fuel as do Shell, but Tesco i think you will find is sourced from Esso! Please correct me if i'm wrong.

I have a P2 and i have used Momentum and V-power (mixed sometimes month by month i change) for 2 years now with absolutely no problems, ever!!

Something tells me d2k you've not fixed your problem. The only way to be sure is to fill her up with Momentum when empty again and see if it runs crap.

how right you are......... the problem has returned, shoddy idle & i aint been near a Tesco's... ??, if i steer the wheel while there's no revs the car stalls, the load of the power steering cuts the engine out..??

i have however discovered that if i remove the batt for 30 mins the car goes back to normal, runs like a charm, perfect idle & dont feel lumpy... but then 2 days pass & the problem returns..?? ive been taking the batt off now everytime it starts playing up ...

can someone please elaborate as to why the car HAS the ability to run normally & does so for a few days then turns to sh.t again..??

is this an electrical problem im looking at, coils failing..?? there's no MIL light either..??

at the moment the car is fine again as i unplugged the batt to wire in my boost gauge, but the problem WILL return....

any ideas lads..... just throw out some hypothetical's...lol , is there anyway to adjust the idle a little higher..??

[LeeT5]

You cannot adjust the idle on a P2 ME7.1 motronic unless you remap.

If I were you I would take the car to an Indy and have them check live readings when it's running let's not waste anymore time or money making suggestions that it could be this or it could be that!

yep you are wrong lol, also wrong about BP an Shell only using their own refineries, i can tell you for a fact i see Tesco, Shell and BP tankers all coming out of Lindsey oil refinery (Total Fina owned) and also Conoco (i think they are owned by Texaco).

Also unless the Tesco fuel was contaminated in some way it wont have caused the car problem, the company i used to deliver samples of these fuels too (Sabolt) who do all the testing for the uk market on all fuels told me Tesco momentum is no better or worse than any of the others and it would be impossible for it to cause engine damage or premeture failure of sensors unless contaminated for some reason, now thats from the experts not me.

i have a very simular problem with my P1 V70, just today we have found the problem, my intercooler is cracked so i would suggest a pressure test on your intake side of things and it was throwing up random codes not related to the real problem

thanks simon........ ill turn my attention to the IC & connections

its worth a look matey, i have spent 6 weeks changing sensors and looking for this problem oh and cost me over £1000 in parts alone lol oh well at least they shouldnt need changing for a while
