Re: 54 Plate VW Polo randomly cutting out

Petrol or diesel?

There should be some fault codes. Do you have an OBDII scanner?

Re: MOT fail (position/fog lamp, brakes, emissions)

Rear O2 sensor replaced. Emissions good enough to pass MOT but creeping up due to a degrading cat.

Re: MOT fail (position/fog lamp, brakes, emissions)

As I set out to have a look at the injectors this morning out of curiosity I pulled of the top belt cover. It seems there is too much play in the main belt as it can be deflected a cm or so just under the pulley using finger pressure. It's possible that the cam belt tensioner has failed or come undo...

Re: MOT fail (position/fog lamp, brakes, emissions)

Found a broken pipe on the breather on top of the camcover that goes into the air box. Taped it up. That might explain some of the smell. Lambda value is still floating around 0.968 with the engine warm Also noted the intake vacuum at idle with the engine up to temp is about 322 millibars Or 9.5” hg...

Re: MOT fail (position/fog lamp, brakes, emissions)

Yes, it smells fuelly but not eggy. I did clean the injectors at the rebuild in Jan 2017. I’ll pull the plugs tomorrow and check the coloring. Could it be the MAP or the Hella CTS (replaced as above)? Temp gauge reads OK, engine warms up OK, hot air on the blower. Drives OK. Last time I checked ther...

Re: MOT fail (position/fog lamp, brakes, emissions)

Correct, there is a MAP sensor on the o/s of the inlet manifold. I did not remove the inlet manifold but inspected what I could in situ. It was refitted with new gaskets and correctly torqued when the engine was rebuilt. I'll have another look and maybe try a cold start spray test. On the previous M...

Re: MOT fail (position/fog lamp, brakes, emissions)

Failed again on emissions - carbon monoxide after 2nd fast idle, at idle, and lambda reading after 2nd fast idle outside specified limits. It seems that there is more of a smell from the exhaust than before. Crankcase breather pipe still attached after I replaced the seals. Sounds like the cat is fa...

Re: Battery question

His battery pack could have been low. He might have simply jumpered the bigger battery at the rear of the car rather than carrying it to the front. Also, he might have tried connecting to the rear bodywork as an alternative ground. It's probably the battery (RAC should have checked it with a battery...

Re: MOT fail (position/fog lamp, brakes, emissions)

Yes, I noted your comment above about unmetered air entering after the MAF but this is entering before the MAF just after the throttle body. I had checked this breather before but did not remove it. What caught my eye was a fine mist of deposits on the elbow. I guess it explains the smell I noticed ...

Re: MOT fail (position/fog lamp, brakes, emissions)

Removed and checked the breather hose from crankcase to inlet manifold. Found that the crankcase end was not seated properly. Fitted a fresh o-ring and refitted. Not sure how this came adrift, perhaps the plastic ring was not positioned correctly.

Re: Polo 9N 2001 1.4 16V Rear brake hoses

After some difficulties I finally got hold of new rear brake hoses. I could not get a TRW product for the o/s and had to settle for Bosch. I was able to obtain a TRW for the n/s. The Bosch came with aluminium washers which were not captive and was an exact replica of the hose I removed - it dropped ...

Re: Leak in Passenger Footwell

Yes, it sounds like you got lucky. Depending on space/access you could try a bottle brush cleaner, a pipe cleaner, or possibly an electrical cable/wire puller (they can be made of nylon or metal). If you could get the latter through (they tend to be several metres long) you'd have plenty length to a...

Re: VW Polo 1.4 9N 5Dr - Beginners mods?

According to a recent news article even stickers can affect your insurance premiums. Undeclared mods can also lead to no pay out and invalidated insurance. What is the odometer reading? I'd suggest to monitor your oil use and do some basic checks to ensure everything is in good order before you spen...
