UK-POLOS.NET - THE VW Polo Forum

last night i was driving normally and all of a sudden i hear a loud thud/bang noise....i pull up and see if there is anything i can see underneath the car. all seems fine....today morning i drive my car and the coolant light comes on. i check the coolant and its well below its minimum. i filled up the coolant....but i think its more serious as i can hear a loud noise when i drive. you only hear it sometimes...i read somewhere it might me the water pump? anyone got idea of something else it might be? any advice would be helpful.

Sounds like the water pump.
If it is then you are well looking at a shocking bill as waterpumps ain't cheap as far as I know.

Well, for the interest of others, what was the root cause of your problem and what was done to fix it?

that sounds like a heat exchanger problem

i THOUGHT the problem was fixed but there was another problem....i had to get the radiator replaced, fan relay and some other bits and the bill came to around £492.00

i hope aj2day you aint got the same problem man.

OK, this is a different cause of shaking but I have a problem with my VW Polo (year 53). I always use unleaded petrol but in a moment of madness, well, it was a long queue at the other pumps, I had used Shell V-Power instead. After a few days, I'm now finding the engine is vibrating and jumping and the gas exhaust warning light comes on in the dashboard. The engine dies if I don't rev but I can't understand why my Polo cannot cope with Shell V-Power with RON 99. I guess I'll have to take it to a garage to drain the Shell V-Power. What a waste of time and fuel! Can anyone suggest a better solution? Thanks in advance!

Keep topping the tank up with normal unleaded - itll be fine after the balance sorts itself out. Some cars dont like 99 ron for some reason - its really odd!

Can't see why rough idle would be down to using super fuel...I would hazard a guess you've got a CAT or camshaft related problem IMHO.
