Thank you both for your guidance and advice. In the end I bottled it and I've just bypassed the heater matrix. The downside may be that I have no heater in the car but I'm very happy to have the Lupo back on the road again

Unfortunately the heater matrix in my Lupo started dribbling into the passenger footwell last year. The car has been laid up since - awaiting better weather and more time for me to fix it. But now the time has arrived and I'm hoping to start work on it this weekend. I am aware that I will have to remove the dashboard to access and replace the matrix. I did download a Lupo manual online to see if this would help. Unfortunately I can't get this to open up on my computer. Therefore I remain ignorant and I'm not sure where to start and what to look for.... So...... I'm hoping some of you guys may and may be able to offer me some guidance?

The heater matrix on my 2002 Lupo SDI started to leak a few months ago, dribbling coolant into the passenger footwell whilst driving. I stuck some radweld into the coolant in the hope that this would cure it - and it did! But only for a short period.... When it started leaking again, I tried this fix again. And again it worked, but only for a while.... So, sadly, it looks like I can no longer avoid the inevitable need to replace the heater matrix I understand that this is a dashboard out job? In the absence of any repair manual for the Lupo, and given my limited mechanical skills, I am in need of some help! I am wondering if anyone on here has done this job and/or whether a detailed 'how to' is available

Nice one I may well be trying some of those tactics myself....

After patching it up previously, a hole has reappeared in my Lupo's exhaust just next to the cat. Don't think I can patch it again, so will need to replace... Decision is whether to replace with or without the cat - and then where to get the parts.... I've seen various conflicting posts around the web regarding getting through an MoT with a de-cat'd diesel. Anyone got any experience one way or other? And anyone got any recommendations on where to get a reasonably priced replacement part? Cheers

I'm also a bit nervous about sticking pure veg oil straight into my tank.... But when you can pick it up for near half the price of diesel per litre from the likes of Costco it becomes more and more tempting. A mix of diesel + veg oil may be worth a wee trial during this summer

I've been running my Lupo SDI on 100% biodiesel for over a year now without any probs. I had to change the fuel filter after a while when it clogged up, but no probs otherwise I understand that all non-PD diesel VAG engines made before 2004 are fine to run on high proportion biodiesel - so its probably a no-no for the Lupo TDI By the way though, 'normal' diesel bought from mainstream suppliers has between 2% and 5% biodiesel already mixed in... From what I read when researching the subject prior to starting to use 100% biodiesel in my Lupo, the main issues seem to be: 1. Because biodiesel has a greater 'solvent' quality than normal diesel, it can 'corrode' non-compatible fuel pipes and joints (this 'solvent' quality is also the reason it cleans fuel tanks and pipes and, as a result, initially clogs up the fuel filter). 2. High pressure diesel pumps (PD or Common Rail) aren't keen on biodiesel. Not sure if the above is universally applicable - perhaps other, more technically experienced folk on here may be able to advise..... Enjoy your cheap, emissions neutral motoring in your SDI

Good shout, cheers Just to point out that this offer only applies to orders over £300....

Is the front panel (in red) housing the indicators available? If so, how much - posted? Cheers.

My 2002 Lupo SDI has just reached 125k...

Now Sold.

No idea what your red cable is...

Top of the cambelt cover? But anywhere obvious/visible really - just have a look around....

Volkswagen suggest changing the cambelt at 60,000 or 4yr intervals on all models (Lupo SDI included) I think.... If there no confirmation in the service book, have a look on the engine or cambelt cover - sometimes there can be a sticker there confirming date/mileage belt was changed. Failing this, better to err on the side of caution and have it changed. The cost is likely to be approx. £250 upwards, depending where you get the job done.

How much for the plastic SDI engine cover, posted?
