Been having this problem for a few days now. When Im going at moderate
speed, and slow down or accelerate, the car kind of *coughs* and its
like its miss firing or something. It also plays up when I slightly
step on the accelerator at low speeds. Anyone know what it could be ?

Have you had your coil-pack done?, if not it sounds like the culprit.

 

[nudda]

damn

some people say its the spark plugs .... ?

is coilovers an expensive job ?

 

[Skii]

Shouldn't be, no. Contact VW uk and see if they will replace them for free as this should have been re-called for this reason.

 

[nudda]

oh right, could you elaborate on that ? So they were going to recall the V5 (150) because of the coils ?

 

[MattyV5]

I dont think the 150 had coil packs ???

 

[nudda]

hmm, what do coil packs do exactly ?

 

[nudda]

so no ones ever had this problem before?

 

[rfsteel]

They provide the power to enable the spark plug to spark, on the 170 V5
you have a coil pack per cyclinder, though as you 150 V5 has HT leads,
it's will be very unlikely that you have coil packs.

Have you checked your spark plugs ? Might be an idea to take them out
to see what condition they are in, it could also be a MAF fault causing
the problem.

My best advice, would be to get it connected to VAGCOM to see if any faults have been recorded.

 

[nudda]

great, Ill check out the sparks and go from there.

Thanks Russell !

Thanks Russell !

Not a problem, should be around over the weekend if you would like VAGCOM to be plugged in.

 

[nudda]

much appreciated Russell. My exams finish on the 16th of May so whenever youre free after then, we could meet up ?

I would start by running it on 98RON fuel if you arent already.

I have seen a few V5's with sticky/burnt valves causing the problem your describing because the 95RON fuel leaves carbon deposits in the internals.

If its sticky valves then long term good fuel and/or conditioner can erradicate it, whereas if its burnt valves they need replaced(expencive)

At the same time it could just be the spark plugs or the ignition leads starting to arc out.

Hope thats a help

 

[nudda]

thanks weelon

could be a start. Which ones the 98RON fuel ?

 

[weeloon]

BP Ultimate

Shell Optimax

These are a guaranteed minimum 98ron but can be higher

Esso have one similar but its only guaranteed 97ron

All other unleaded fuel is 95ron unless clearly stated otherwise.

 

[nudda]

thanks weelon, will give it a shot.

Hi Nudda,

I just did a search on 'spluttering' and this post from 2005 came up.

Can I ask if your coil light was flashing when you had this problem? my cars just started spluttering at low speeds too, did you ever find out what it was?

please let me know, it's driving me nuts!
