The only way I could see to get my hands on the actuator was by removing the manifold and maybe even the EGR. However, since I had no idea were the actuator was located, I may be wrong in identifying the small bit, that was visible, as the actuator. Tomorrow I shall be downloading Elsawin and hopefully this will help me in locating it. By the way, was yours a 1.4TDi when you wiggled it with a spanner?

It was impossible to view or get access to the Turbo actuator. I took the Lupo for a boy racer short journey. Initially the engine was wimpish, lacking power. However, after a few punishing miles the power returned back to normal. Throughout the journey the Engine Error light never lit up. My guess is: normally I'm a Sunday driver, hardly ever going over 60 mph. Got a feeling carbon deposits built up causing a wimpish engine. Thrashing the engine on a short journey must have cleared the deposits.

I will look at the pivot point, in a few days. I shall be back to tell the tale.

I think I know what RIch did. He probably used the spanner on the pivot point moving it up and down, which then pushed the actuator rod in and out and eventually freeing it.

Rich. I have heard about turbo actuators problems on VW's. I am confused about using the 14mm spanner. The actuator rod moves in and out not up and down. I do not understand what and how you moved the rod up and down? I have seen new actuators from China for about £23.00 but as yet not looked at the car and was wondering if it worth getting one and how easy to install?

The 2004 lupo has 100,000 on the clock. Last week Engine warning light came on. Checked the fault codes and found just one code error - P0299. At the same time the engine became sluggish - losing power. This DTC error relates to Turbocharger under boost problem. Anyone had the same problem?

My mistake, I meant the Exhaust system warning light. It is the petrol version that has the Engine management light.

Two years ago had a similar problem with my 1.4Tdi. The EGR valve was all sooted up. Had to replace the EGR. Been fine ever since.

Had a look at the back of the engine, it is tight but I will have a go removing and cleaning the manifold. Thanks. I thought of cleaning the EGR but Ridex EGR is around £30 see https://www.buycarparts.co.uk/ridex/8095043 so will go for it.

Looking more carefully under the bonnet, I agree removing the flexible pipe is a must. I am now more confident in giving it a try. Is it not dangerous to try and clean the inlet manifold? if you accidently drop something into the inlet it would go straight into the cylinders. How did you clean the manifold?

Empty

Thanks - Does the flexish pipe stay in position or do you have to remove it? Looking at the flexish pipe flange, even if you remove the two bolts on it, the flange looks like it will prevent you from removing the bottom EGR bolt. What type of allen key did you use, because this flang does not leave any room to put the allen key into the bolt head? Or when you undone the two bolts on the flexish pipe did you push the pipe out of the way then access the EGR bolt? Or did you remove the flexible pipe altogether?

I want to remove and replace my Lupo 1.4TDi EGR valve. However, the bottom EGR bolt is almost impossible to access because there is the exhaust\EGR flange right next to this bolt. How did you mange to undo this bolt and what tools did you use?

Has anyone managed to remove the EGR valve from a Lupo 1.4TDi.? Three allen key bolts hold the EGR to the manifold body. The top two I can easily reach, however the 3rd, at the bottom, is difficult to access because just in front of it sits the EGR/Exhaust flange bracket preventing me from acessing/removing this bottom EGR bolt.

The car works perfectly well (95k on clock) - no misfiring or sluggishness. If it is only 3 bolts to remove the EGR I might give it a clean. If I replaced with a new EGR would any software need re-mapping. Finally I will take it on the motorway, as you suggest. Since covid began almost stopped using it, so have not gone above 50 mph is two years - 150 miles in total. I will also delete the EGR error code and see if it comes back. If it is the camshaft, I got no way to check, then it would have to be goodbye. Incidentally the cambelt got changed at 75k miles.
