I'm thinking of buying a diesel Karoq. I believe recent ones have the Adblue system.  have a different make car where this is very unreliable, so I had it deactivated with an engine ECO optimise. THe MOT requirements are met re. warning lights etc., but I've no more hassle with spurious 'engine won't start in 700 miles ' type messages. Does anyone know if something similar works on the Karoq 2.0 diesel, and do you have any comments about the AdBlue system on these cars?

Any particular reason you must have diesel?  High Mileage? Towing?

 

Anyway the EA288 2.0TDi is fitted widely across VAG vehicles. A few issues early on the NOx sensor but generally a reliable unit.

 

I just swapped from a 2.0TDi 150 EA288 to a 1.5TSi 150 EVO2 EA211.  To be honest I've probably had my last diesel.

I've only had experience with WV (Skoda is same or very similar) and Peugeot with AdBlue. Latter is horrible with it. It's a company car, and almost every time it's time to fill the AdBlue tank, throws all sorts of errors and emission faults. Garage visit needed to fix it (not sure what they're doing with it). Also on the Peugeot, the range is a lot less than on the Skoda.

 

On my Karoq, 10litres of AdBlue is for around 5-7000 miles depending on the usage. I do service every 6k miles, with that the AdBlue gets topped up. Not a single fault or issue so far with the system on the Karoq, apart from the reminder message from the 1000 mile mark.

It is certainly possible to map it out, but until it's giving me a headache, I'm not planning to do it.

I like diesels with autos, because the torque usually means they don't change gear much and run at low revs, making progress very relaxed. I do the 270 mile run from Guildford to Falmouth a couple of times a month. Even on hilly roads my current 8 speed DSG Berlingo diesel very  goes up most hills at 2000 rpm unless it's heavily loaded - but that car's noisy with far too much road rumble. Interestingly, with the Karoq it looks like a choice between the 2.0 116hp 2wd diesel or the 1.0 petrol. It seems the adaptive (! - must be adaptive) cruise control, a wonderful thing on the A303 run, is as rare as hen's teeth on any diesel, but slightly more common on the 1.0 petrol engines. I can't figure out whether there's much in it on fuel or not - on that trip any car will often achieve an MPG figure near to the best theoretical one in the brochure, but the 65mpg given for 'out of town' on the 116hp 2.0 diesel sounds a bit...Volkswagen ish: )

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Prior to the Karoq I had a 2013 2.0 TDI 140 bhp DSG VW Touran, at 70 mph on A and M roads on journeys over 50 miles it would regularly do 60 to 65 mph. I only ever used Shell V power diesel though.

@Maxr Welcome.

Your Citroen Belingo diesel has a EAT8 Automatic gearbox, a torque converter box, it is not a DSG.  Twin Clutch Semi Automatic gearbox. 

 

You should maybe try a Petrol with a DSG and see how it performs.

I think you'll need to choose carefully.

 

Your Berlingo will have 130PS and 300NM @1750rpm.

 

You are looking at the Karoq with either the 2.0TDi 115PS and 250NM @1500rpm  or 1.0TSi 116PS and 200NM @2000rpm.

 

So power and torque wise both are a step down from what you have now.

 

Why have you discounted the 1.5TSi?  150PS and 250NM @1500rpm. With active cylinder technology economy is very similar to the 1.0TSi but performance is significantly better. It has the same low down torque as the 2.0TDi 115 but significantly more power.

I guess the 1.5Tsi is probably quite close in power etc to what I have now  - the current Berlingo diesel was ECO optimised when they shut off the AdBlue system, so it's possibly now 140 something bhp, dunno how the torque changed. Ootohere  above is right, the Citroen auto box is an EAT, not a DSG. The 1.5Tsi also appears to be the most common engine in recent used Karoqs, so I'll have a test drive. I was thinking diesel because our other car is. In the past I've sometimes had one diesel and one petrol, and yes, I've put petrol in a diesel one 😞 Thought I was just being stupid till the garage sorting that out cleaned the system and refilled it with the wrong fuel again...

Interesting - I didn't know there was 116PS 2 litre diesel.  How do that get the power ouput so low?!  😀

 

We had that engine (assuming it's EA288) in Tiguan DSG 4Motion with 150PS.  It was fine, but I wouldn]t have wanted anything less powerful.    Got rid of it at 8yrs old when could no longer renew the All In cover and the emissions stuff on the car terrified me - not just the AdBlue, but it has 3 cooling circuits and 2 coolant pumps.  It used to regen a lot too - around every 200 miles - and we always ran it on Shell V Power which was eye-wateringly expensive (but only used a tank per month).

 

The 1.5TSi Karoq we have now I'd say drives very similarly.  Car is really my wife's and she does mainly semi-rural running around, few miles to shops and schools etc.  I track the MPG and overall it's the same as Tiguan was at calculated 38MPG.  Tiguan would just about touch 50MPG on a long run.  Karoq will surpass that if put in Eco drive mode (usually use normal).

 

Although the cambelt and water pump time change at 5yrs has officially been done away with it seems a lot of folks reckon it's still worth doing on the diesels but less vital on petrols.

You do away with the 1.6 and map the 2.0 to the same power and torque.  

 

Limiting the torque to 250NM means cheaper gearboxes and running gear.

 

All about Market Placement.

 

Diesel market is small now. Just 6.5% of sale in the UK so cheaper to offer one engine in different power outputs than a 1.6 and a 2.0.

The 2.0 TDI,s with 116ps use the DQ200 DSG, In VW Golfs as well. 

Pretty good fuel economy from them, but 1st gear to 2nd is a PITA. 

 

This economy was just after collecting it and back roads home.

Hire car, but over the time i had it it still did amazing economy even on motorways.

Do the 116 and 150bhp 2.0 diesels use the same auto boxes? I noticed one of the chip tuners 'eco' tune (stage 1/2?) gives 180-odd bhp, if I remember correctly, for both engines.

Plenty have had cars remapped with a DQ200 DSG to over 200 bhp & 300 + Nm.

1.6 TDI,s and 1.4 TSI Twinchargers, 1.8 TSI,s.   The DSG can be remapped and uprated clutches fitted.

 

But then you could just get the car you need in the first place and have a warranty.

No the 116 gets the dry clutch DG200 and 150 gets the wet clutch DQ381.

 

DQ200 is rated at 250NM, DQ381 is rated at 430NM

If you are thinking of a 4WD Diesel Karoq, beware. Because of the rear differential taking up space where the adblue tank, and controller fits, they have had to move the control unit, would you believe, to be under the rear offside wheelarch! Guess what? It gets water in it, shorts out, flattens your battery at 3-10 in the morning and costs £300 for a replacement unit. Fortunately I have a warranty. (the units are £45 on ebay!) I didnt know but adblue freezes at -11°C.

Thanks Elegant70: I was thinking of the 116 bhp 2.0 2wd diesel, which claims astonishing fuel economy. I mostly drive out of large towns, and IF it's as good as Skoda claim, that should be good for 70+mpg on a long run. However I now know that many of these are bought by high mileage drivers, there aren't many about, and even fewer have adaptive cruise control, which I want. I might end up with a 1.0 dsg SE L Tech with ACC if I can find the right one.

The VW Golf had amazing economy when i was using one.

But the 1st gear with the DQ200 and the TDI 2.0 116 ps engine was a total PITA as the car died as it went from 1st to 2nd, so i was always in S for trundling about in town.

 

Plenty cars with SCR / ADBlue are used in ambient temps well below -11*oC,   Even in the UK.

If 4 wheel drive, control unit is under rear offside wheel arch, would you believe?!. Gets damp, shorts out, flattens battery costs £300 to replace. £45 on eBay but not warranty compatible.
