VW Polo 2003 Automatic Transmission - Advice on buying a used car - abby04
Hello everyone! I just bought my first car, a used one from a garage I found on AutoTrader. Everything seemed fine at first, and it still drives well, but I’ve noticed three warning lights have appeared on the dashboard. After some googling, I’ve identified them as the check engine light, the EPC light, and a brake warning light (a red exclamation mark inside a circle). When I turn the engine on, there is sometimes a loud, awful screeching sound which I’m not sure is related to these warning lights.

I don’t know much about cars, and I bought this one to get more confident driving and just to get from point A to B. I’m still a young driver, and so I can’t really afford to do too many repairs, and I feel this is unwarranted especially since its only been a week since I bought it. I even have a photo that shows the dash lights on, and the mileage at 89994 (it was 89974 at its last MOT done this month before I bought it). I know it’s a very old used car and so I cant expect anything too perfect, but I think 3 warning lights appearing 20 miles into my owning the car is crazy. The dealer reassured me that the car was well-maintained, had no problems, and that I wouldn’t regret the purchase. Now I’m starting to feel like I might have been sold a car with underlying issues.

Is it normal for these lights to stay on? For context, they turn off when I’m driving but stay on after all the other dash lights turn off. Can I ask the dealer to fix these issues for me, and are they legally required to agree? What are my next steps? I’ve already bought my insurance, and taxed it for the year. I’m sorry for all the questions. It’s my first time dealing with anything like this, and I’m feeling a bit overwhelmed. Thanks in advance for all your help!

Hello! How much did you pay for this 21yr old Polo?

I paid £1800.

The dealer reassured me that the car was well-maintained, had no problems, and that I wouldn’t regret the purchase.

For future reference, remember these three points:

1, All car dealers are liars

2, All car dealers are liars

3, See points one and two

Now the above may be slightly unfair, but you need to get the gist. They run a business, and in order for that business to survive and for them to make a living, they need people to buy the cars they sell. So if there is a car on their forecourt which is a dud, they aren't going to tell you that are they?

You can help yourself to an extent by checking the MOT history online (here check-mot-history all you need is the registration number). This will give an indication of how well the car has been looked after and alert you to possible future problems which need to be addressed or keep an eye on.

On the plus side, a Polo of this age is a fairly simple device with a n/a (non turbo) 1.4 and a t/c (torque converter rather than a complex and fragile dual clutch DSG)

I’ve noticed three warning lights have appeared on the dashboard. After some googling, I’ve identified them as the check engine light, the EPC light, and a brake warning light For context, they turn off when I’m driving but stay on after all the other dash lights turn off.

Can you expand on this, its a little unclear?. Seem like you are saying the warning lights go off when driving but also stay on?, can't be both!. When you start the car, it will go through a series of self diagnostics to check if everything is as it should be. That is why the warning lights come on and then go off again. If they stay on (or come on) while driving, it is a problem, otherwise it is fine.

Screeching noise will probably be a slipping belt. I'm not sure how big/expensive a problem this might be. You'd need to get it checked by a (reputable) garage.

When I turn on the car, all the dash lights come on briefly and then turn off but those 3 remain. However, when I twist the key fully and actually turn on the engine they disappear. So, while I’m driving there are no lights. Do I need to get this checked or is it normal?

Book it into a good independent garage for a major service and highlight your issues at the same time.

I’d get it back to the dealer . It could be a fairly easy fix . A faulty brake light switch could cause this issue, very common on Vw models .

It rather sounds like there is nothing wrong with it at all. Have you actually looked up in the manual what the brake light means?

If you are unsure try asking the dealer if they can code read it for you and check but to be honest this sounds fairly normal.

So is it normal for the EML light and the check engine light to stay on after the others but turn off when I drive?

If the lights are out when driving, it's fine. The horrible screeching sound when you start it up is probably an accessory belt and not a big drama

Take it into a decent independent garage, give them twenty quid and ask them to start it and let you know if they think there are any issues. If there are, take it back to the dealer to either resolve or refund.

All warning lights should extinguish within approximately 10 seconds of starting the engine. Unless , of course, you’ve got the handbrake on .

Another guess on the noise would be the starter motor which seems common on VAG cars of this era.

It's not a big thing - you might be looking at a new starter at some point but on a 22 year old car things will need doing.
