Sorry to ask this as I expect its been asked many times before, but I cant find the threads.

Its been brought to my attention by the wonderful Skoda garage that I need a new knock sensor. Is this difficult to get to? (believe its at the back of the block (1.4 16v)) and wheres the best and cheapest place to source?

Thanks in advance

Can't help on location, but GSF Car Parts, cheap car parts direct to you and Euro Car Parts UK - European Car Parts should be able to source one for you

Yep back of the block in the middle under the manifold. MUST be torqued correctly for it to work.

Thanks for the replies. How difficuilt is it to get to and torque up? Should I put a whole day aside to do it?

Is this on your BZG? 

What makes you think it needs replacement?

Tenth photo in this listing shows it just below the plastic coolant pipe going across the back of the engine:

thank you wino

 

i have made a thread already

 

 

the symptoms i am getting is very similar to my previous car which is sluggish on start up and pinging/knocking noise.

Hmm, it would be a lot easier to get at from below. You'd probably have to remove inlet manifold, fuel rail, injectors and all sorts to do it from the top.

Fault lights on?

ok so if i do it from the below, i would be able get to it straight away without anything blocking the way? am i right?

that is the thing, no fault lights at all, i would have thought it would pop up but nothing, yet i am having the symptoms of a dodgy knock sensor.

Without a fault code read, I would say you're probably wasting money and time swapping sensors out on a hunch. If it is the knock sensor, I'm pretty sure a fault code would be stored.

Find a member near you with VCDS and get it scanned.

i like to try scan it myself, is there a budget one you could recommend please?

Sorry, I have no idea what works on a mk2. Full VCDS surely does but that's proper money.
