I already did that in the previous post (valve overlap). The inlet camshaft has a hydraulically operated adjuster. By changing this adjuster, the inlet valve opens earlier, during the last part of the exhaust phase. In this way part of the exhaust gasses are blown into the inlet, and reused.

This advice is useless. Please learn how the EGR of an 1.8 TSI works before giving wrong advice...

The 1.8 TSI doesn't have an EGR valve, so you can rule out that one. (EGR is performed by valve overlap).

Specifying your engine type might help... (2.0 can be TDI or TSI...)

Problem is that we still don't know whether the rolling diameters of the tires were in fact different. After all, the circumferences of 205/55R16, 225/45R17 and 225/40R18 are all almost identical, so mixing these dimensions will not lead to premature wear of drive components. So unless @MarkyD answers my previous question above (regarding the exact mounted tire dimensions), answering his original question is impossible.

Without knowing the exact tire dimensions that the car was on, this question can never be answered.

@Baliii Have you measured the voltage levels at various positions? What is the battery voltage?

I'm following all news of the 1.8 TSI since 2010 on several forums, but never heard of a crankshaft seal issue. Mine was replaced in 2020 though, when my engine was revised due to the well-known (but not in 2010 😒) oil-consumption issue.

That's the comfort entry / exit mode as mentioned by @tuningmaniaabove.

You have to use one or both of the blue connectors. But you may have an issue with power for the antenna amplifiers. Does your new unit supply power on the antenna cable?

That switch is part of the AC and ventilation control panel. You will have to remove that panel completely. And than, if you want to get to that specific switch, open the panel, probably from the back side.

The engine will handle this just fine. You're not even towing a caravan! The biggest problem will be the total weight. With four over-size adults, a full boot and a full roof box, you will almost certainly be over the max weight of the car. Suggestion: Use a small trailer instead of the roof box for the extra luggage.

Whats wrong with that picture? I find it perfectly clear. Simply choose the row with your tire size, than the part with normal load, or fully loaded. And then below that the left column is the pressure for the front tires, and the right is for the rear. No problem at all.

I agree you mentioned it can be coded (sorry, should have read your post better). But that does not mean these tyres can be fitted on an S2. 235/45R18 is the dimension for an S3 and simply much too large for an S2.

That is not correct. 235/45R18 has never been available on an S2, but is the tyre size of an S3. The largest size you could get on an S2 was 225/40R18.

Those have a much larger diameter than normal on an S2. I doubt if they fit.

P0016 points to a stretched timing chain (especially for a 1.4 TSI...). I would go to a VAG-specialist or -dealer to have it looked at asap. If the timing chain jumps over the gears, you need a new engine block... Also the fuel pressure is most likely generated by the cam-shafts as well (at least, that's how it works in the 1.8 TSI), so there is definitely something wrong in that area. What does a VCDS-scan say?

That's not really a solution for the majority here who are looking for something newer than the outdated V17...

Did the map update for the Columbus from the above mentioned site actually work? If yes, where did the data come from? Since there was no release since the West Eur V17 version, the data must originate from somewhere else. Or did they simply relabel the old V17 as a newer version and sell you the old data? Did you see any differences between V17 and these maps?

But exactly that was explained in instruction no 32 of the instructions that you added to your post? How did you miss that? (Since it was indicated so clearly in the instructions that you yourself provided, it did not occur to me that you did not do this)

(Irrelevant to your case, but be aware the VAG uses software to keep that temperature gauge at exactly 90 when the real coolant temperature is between ~75 and ~110°C.... If you want to know the actual coolant temperature, you need VCDS or a general OBD device)

Do you have a petrol or a diesel engine? Might be relevant to mention that...

Thanks, that's good news! Removing the premium bluetooth is no problem, since I cannot use it anymore anyway.

Is that MIB STD2 PQ from Yeti FL also possible if you have an S2 with a sound system, and premium car kit (which is not premium anymore, since 3G has been cancelled here in NL)? Might be interesting for me, since I plan to keep driving my 2011 (MY2012) S2 for another 5 years.

A few tips for you: Read the user manual! It's there for a reason, and clearly describes what to do in case the mentioned fault message appears. Stop shouting. We are not the cause of your problem, and not very eager to help people shouting at us. Use Google before starting another thread similar to older threads describing the exact same problem, and the solution.
