Doris is a 2004 Lupo 1.7SDI, with 101,000 miles. Recently, my daughter has had the following happen to her twice; turns the ignition off, resulting in a "whining noise" (like an electric motor) and "gurgling" (like water flowing). The digital clock and trip meter both reset to "0", and if attempted the car won't restart. After 10 or 15 minutes the car will restart... anyone else experienced anything like this or any ideas what the fault could be? Thanks  |

As the car is relatively newer i suggest getting it on a code reader (VCDS or similar) to see if there are any fault codes first, otherwise you'l get a load of spurious guesses dressed up as diagnosis.

Thought they had gone to the 1.4 TDI by 2004?
My son has a 2000 Arosa 1.7, SDI which is more or less the same car. It always makes odd sucking noises when switched off (possibly your gurgling?). We found it alarming at first but it seems to be a feature rather than a fault - at least it's been doing it 18 months / 10,000 miles.
Can't explain the whining though. It does seem to be a little "delicate" electrically. One of the issues was a failed ignition switch (VERY common VAG fault) which could just possibly be related. You could try getting the codes read but the electronics are not very sophisticated on these.

First thing which sprung to mind when reading the fault description was faulty ignition switch. The lupo shares a lot of running gear withe the 6n polo, which was very prone to burning out the ignition switch, resulting in the car that sometimes starts and sometimes appears to emulate having a flat battery.

Its an 04 so will be OBD2 get all the faults cleared and rescanned after a couple of days,
Could be anything from vacuum to air locks sometimes just clearing any codes sorts things out like that...
Get on to tdiforums or ukpassats etc and see if anyone has vcds in your area???

Had a similar thing on my Polo (6n2 2001). Failing ignition switch. Replaced at my local garage (mates rates) for £70.

Get it code read, other than that check the battery terminals are tight, possably loosen then, twist a few times on the posts and re tighten.
Do these have aux leccy water pumps? low coolant level and a leccy water pump can make this noise?
Other than those another vote for the ever weak VW ign switch BUT (and i meen this in the best possable way) try and hear the noises for yourself, i find people (not just women) who have no real interest in cars can mistake an obv sound for something way more interesting, my Ex once told me the turbo was on the way out when the heater fan had a leaf in it and the noises my (otherwise deaf) mother can here is amazing if way off the actuall noise.

Safer getting it scanned by VW specific reader as generic readers sometimes misread VW codes. That readers ok for petrol motors and newer type dervs.

I may as well warn. The statement below is out of context a little but somehow relevant  . It it helps. I had a cheapo reader on my 2006 B6 Passat. It read no codes whatsoever. On VCDS the outcome was somewhat more depressing. The codes went along the lines of the following: -MAF sensor recording low air - It was! -Overboost issue -ESP issues -ABS issues -Steering lock issues - intermittent -interival Wiper issues - intermittent The first two issues were down to a severely worn camshaft but if I got a pound for every person who said I had a knackered MAF and a turbo. The car basically was misfiring horrifically on throttle and left a cloud on black smoke simultaneously. The ESP and ABS issues were down to a pair of very worn rear track control arms ; it had a horrific twitch on the rear before they were change ; I had never experienced that bad a twitch on a car before. People moan about the Triumph Stag 'twitch'? Try a Passat B6 with the rear bushes fallen apart to pieces! The latter I have to say was a simple - The stalk was knackered. Likewise my Alfa had a billion warnings on the dash warning of engine issues. It recorded nothing on the OBD scanner. The issue was simply down to a leaky intercooler hose . I guess what I am trying to say in a nutshell is that the codes give you an idea of what is wrong, but under the wrong hands you may as well throw reddies up in the air. |

My brother's polo of a similar age used to do the not starting thing. If it was left for exactly an hour, it wouldn't start. Ten minutes more or less and it was fine. I never got to the bottom of it and the only fault code it ever showed up was a faulty cat.

If you are buying purely to use on the lupo, I wouldn't bother. The lupo is old tech. The chassis is a chopped down polo 6n, which in turn is based on the mk3 golf chassis, which from memory isn't hugely different from the mk2 golf. The engine and running gear is equally as old. Tried and tested you might say! My point is (as someone else has pointed out) the electronics and diagnostics on these are basic by modern standards. It won't give you much help and in any case, you'd be better off just changing the ignition switch anyway if the car has never had one done, as it will fail sooner or later and trust me, it is a total pain when it completely fails. |

I've got full VCDS and in Essex if it's of any use to you. Snap on code readers (and thus cheaper ones) don't pick up on half the things that VCDS can so it's worth while getting it scanned and having everything reset (half the time things aren't deleted when they're rectified), then as others have said drive/wait and see what returns on the next scan.

I had my first experience of this last night, after cleaning the car. No gurgling noise (as the car hadn't been running) and the "whining" sounds identical to winding the mileage on an analogue clock. Left it about 15 minutes and still wouldn't start so put the booster pack on and she started straight away.
It's the original (2004!) battery, so I think it deserves replacement as a first step!
