Well, I decided to do the old Throttle Body clean today and oh my word the amount of crud and soot deposits in there was ridiculous.

After looking a quite a few vids on how to do do it and may I say making it look like child's play, I decided to give it a bash, after all, how hard could it be.....right?

Wrong!! Unless you have arms like Stretch Armstrong (reference for anyone over 40) and hands like a schoolgirl, this is anything but easy. Fiddly is an understatement and the lack of room is quite something.

Anyway, rant over about the supposed difficulty level (or my lack of skills) take a look at just how manky it actually was.

Title Change

Interesting to see this and well done on getting this done. Have you noticed any difference in performance / response ?

What mileage is your car ?

I see someone else had posted up a while ago on this process, it all sounds easy/straight forward but likely never the case...!

The car is on 106000 currently and maybe a slight increase in response but not really in general performance, probably because once you have your foot down thw valve is still open. Feels a bit smoother pulling away and glad I did it but I will be modifying the EGR valve to stop it putting soot/carbon back into the Throttle Body. Terrible design!

Good job! But what kind of engine does your car have? Is it a 2.0 TDI?

Yes mate, 2.0 tdi on a 63 plate 140bhp

Good job well done. Yes it is quite a bit fiddly...and you description is quite spot on 😆

I did mine a couple of years ago, as I have a petrol, it was not bad at all, pictures in previous post.

A bit fiddly but worth it.

I was wondering if the state of our throttle bodies is an indication therefore of our injectors etc?

From what I understand the main reason the TDI's get massively caked is due to the EGR valve facing backwards towards the Throttle Body.

Not too sure about Petrol ones other than the fact they burn cleaner?

No, not directly related. Earlier versions had a construction fault that was corrected in later versions. I believe this was fixed from 2013. The exhaust points towards the air inlet instead of towards the engine manifold side. So 180 degrees wrong. Many people have fixed this by modifying the connecting pipe adapter into the throttle body. It is a thread about this in the guides section.

They do burn cleaner. Prone to carbon build up, but luckily on get my car up to temp a lot due to location.

My TB after its last clean 15k ago. To be honest it was in really good shape before the clean.

Found and easy way to replace the hose also.

Mine is a 2012 2.0tsi, hopefully all good.

I am going to sort out the EGR soon, will cut the notch on opposite side etc and turn it around.

Yup, good call! Did mine last year. I used a Dremel like 12v Milwaukee tool.

Can't i just cut it out with wire snippers?

Any pictures and HOWTO available

Just an update here but I have been noticing for a little while that I get a slight shudder when pulling away (more obvious when cold - and its not the clutch as was inspected recently) also the old hesitation then bang you're off. This happened last time before I cleaned the Throttle Body (when I had the P0121 code pop up on my Veapeek)

But..... I have been researching a little more and this could all be signs of the TPS.

I can get another for not too much cash but wondering if there is anyone near me (Norwich) that can do the Adaptation needed after I fit the new one myself??

Any help would be brill

Okay I have bought the OBDeleven 2 pro so I should be able to do adaptations now.

Is there a guide anywhere?
