hi from uk check the main lead from battery+positive to the starters solenoid is secure ? also there is a thin wire that also connects to solenoid on a terminal of its own this is the solenoid energizing wire that works starter when key start position is selected if all above is ok? then use a jump lead and connect one end to battery negative post then the other end of lead to a suitable earth point on engine ? then try starting? if it works/starts ? you have a bad earth connection to engine from battery negative lead check the earth lead connection at point on engine is clean/secure ? it usually is secured by bolt at point where engine and transmission connect ? hope this helps?

SOURCE: vw polo vibrating inside the car??

Sounds like one of your engine or gearbox mountings are faulty or broken, Check them and try moving the motor with a long bar, if they are broken you will soon see it.

SOURCE: lambda probe fault possibly

I bought a 2000 polo 1.4 yesterday after having an MOT. The warning lamp came on today but the car is running fine. Whether its the Lambda sensor or just the light itself is a common fault, I think garages turn off the lights to get it through the MOT then they come on again in a day or two!

hi.
if there are no faults showing, then the most obvious thing to do would be to change the air filter, this is a relatively cheap part, but it can make a huge difference to emissions, even if it looks perfectly clean.
also make sure you take the car on a good run before taking it to the test centre to ensure that the engine and catalytic converter are up to operating temperature.

it is possible that the catalytic converter is clogged up and not working properly. the only cure for this is to replace it. the mot tester can usually tell you if he thinks it is the cat. my mot tester is always good for advice, just ask what he thinks could be causing it if the air filter does not make enough of a difference

Which engine oil? vw polo 51 reg


The VW specs for oil is way over-hyped.

Use a Brand Name Full Synthetic 10W40 oil and you'll be OK.

Ford Mondeo failed its MOT exhaust emisson test


The advice that the garage gave you seems right. If any bushes were worn they would show up on the MOT Test. Try taking it to another garage to check out the Cat for your peace of mind.
