UK-POLOS.NET - THE VW Polo Forum

I have a VW Polo 1.6 GLX 1996 (P Reg) 74,000mls.

The car runs well apart from a niggling problem of cutting out intermittently.

I can be driving along fine and the engine/ignition just cuts out - I pull into the side of the road, switch off the ignition, switch on again and the engine re-starts immediatly.

It sometimes dies as though it is about to cut out but I can (sometimes) manage to get it to cut in again if I change down a gear - this can happen 2 or 3 times within 20 or 30 yds and then it will drive great for the rest of the journey.

I have recently had a diagnostic test which gave an error message of "00519 ma,fold Absoltute Pressure Sensor Not a plausible signal occurs intermittently"

This resulted in having the M.A.P Sensor replaced.

However, yesterday I took the car on a journey (approx 40 mls round trip) within approx 1.5 mls the problem returned, the car ran great for a further 15 mls before reoccuring.

It is allways when I am in 5th gear and mostly when going driving up hill.

This is the general pattern of things.

I would appreciate any suggestions on how this problem might be resolved.

Hi mate,

Unfortunately i've got a similar problem with my 6n 16v as it idles around 850revs and sometimes cuts out. had sparks, leads, throttle and distributor changed with no change. diagnosis red 00529 'missing speed signal', you can C what that means if its any good but i'm taking myn to Bog Boys Toys to sort it out.

Let me know if yoou fix the problem

Hi NOZ

Thank you for your input.

Just to update you - the car has been running fine now for a couple of weeks however I didn't want to get back to you untill I had given it a decent journey - I have just come back from a trip of approx 100 mls and the car has been faultless.

What do I put this recovery down to?

After the garage had had a couple of attempt to sort it out (at a cost of approx £80 to £100) I decided to try something myself - wait for it ...... RedX ... and I have had no trouble since - cost under £3 .

Hope your problem has been sorted.

musta been dirty injectors or something like that

It happened again today!

The day after I put in £10 worth of Supermarket (Tesco) petrol, which has got me thinking about my next move?

A. Should I stay off Supermarket petrol or

B. Should I upgrade from 95 to 98 octane or

C. Go back onto using RedX.

I would appreciate any thoughts on the above.

Thank you.

Hi, i have a polo 6n2 1.4 and my engine kept cutting out when i dropped to low revs. after investigating i found out that it was a substance that had built up in a tube heading to the throttle body or sumink from the air filter. cost me £20 to fix and havent had a problem since in months. Hope that helps

ok guys, little update with mine.

For ages I hadn't done anything but the other day I made a trip to vw so thought i'd get a temp sender for £28. However, it hasn't made any difference other then doing it slightly more!

The next thing on my list is the idle control valve, a new one comes as a whole unit and costs around £300, which won't fork out. I need to know what the parts actually are so I can have a look at my one. Anyone able to shed some light or have pics?
