Had a 2.0 Diesel Tiguan, same model as you. No oil consimption at all over 80.000 km.
Changing the spark plugs, spark plug wires, ignition coil and the coolant temperature sensor fixed the cold start issue.
I actually just changed the pump on my 2018. With the pump/thermostat assembly, and a collection of specific tools, it cost me ~$900. I was quoted 2k by a dealer so I saved a good chunk of change. All-in-all the job is straightforward, save plenty of headache with disconnecting hoses and wire clips.
Ayyyy something to check ik it’s two different vehicles but my 2012 Passat ended up doing the same thing and one mechanic told me a new engine but thankfully he send me to euro shop for a second opinion and wala what I thought the car was toasted it was a camshaft position sensor
Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone
Diesels have better economy and decent torque, but I don't like the kle-kle-kle and shaking like a crackhead. Also, they cost more to maintain so fuel economy goes out the window at certain point. Glow plugs, DPF, EGR, injectors seizing up are pretty expensive things to change.
You should not drive them short distances, they like getting hot and ready for chugging along for hours, otherwise the parts mentioned gets clogged up quicker.
I had a tdi and it was great getting 40 miles on a tank no matter how fast I drove, I did not delete anything , I would not do that and even if I wanted to dot my state would catch me, fuel is generally but not always more expensive, up there with premium , the big gotcha with my two wa snot that they cheated but the high pressure fuel pump was a ticking time bomb, I went through 3 of them, and they were fuc\\*\\*\\* expensive, like several thousands dollars to replace, I bought my car brand new and took care of it , the first one dies around 65,000 miles or about 2 years of driving, vw paid for that , the shop bill was 5 k, the best one dies on my about 120,000 miles and that was on my dime, cost me about 1800 and that was with a donated HPFP and not draining the gas tank 100 %. which is not the proper way to replace it but at that point VW was already buying mine back and I just had to get it there in running condition. I also would have needed a new DPF which VW wanted about 2 k to replace.
The battery VW uses in the ID.4 is trash. I had it replaced under warranty in my 2021 after about 2 years when my car died in the garage and I had to get assistance. The tow truck driver got it going with a jump starter. It\u2019s now just out of warranty in year 4 and I get the \u201cLow 12V\u201d warning on cold days.
And don\u2019t get me started on that terrible cabin air filter placement\u2026
I personally warned someone considering this car not to get it for their family based on this video alone https://www.jalopnik.com/1925823/volkswagen-id-buzz-complicated-cabin-air-filter-replacement-tiktok/
