Would like to give a few pointers. Hope these helps so you can enjoy your ownership. I'm an owner of multiple big Citroens. Currently still driving one on daily basis.

SUMMARY : In short, I would say treat a Citroen like a French girl. They have attitudes and their own requirements. They are proper continental cars, cheap to buy expensive to maintain. They're not for everyone. But if you love designs and novelty, and you can feed them properly, they will return your love, in a big way. If this is your first continental car, I would advise against buying a Citroen. Also, if you care about Resell Value, stop reading now. Citroen isn't for you.

1. Prepare to deal with spare parts down time. Do not believe in stockist or Naza warehouse. Major spare parts are mostly directly brought in from France upon placing orders. Place orders earlier when there are symptoms (usually technician will inform during service intervals), do not drag until last minute. Expect 1~3 months down time for major issue. Personally I had experienced 6 months down time after accident. DS5 is introduced worldwide back in 2011, expect even lesser support starting from 2021.

2. My current daily run on a THP engine, with full Naza service record. You can send to outside foreman but do at your own risk. First issue is extremely hard to find a someone that specialised in new Citroens. Especially newer and bigger Citroens are designed to be quirky and odd inside and outside. Secondly, you're losing your warranties. There are a standard 5 years warranty and extra 2 years warranty. The latter only covers your engine and drivetrain, but Naza / Brooklands service record is one of the requirement.

3. Why is the extra 2 years warranty important? Because to replace the turbo + peripherals alone will cost you RM12k. Rocker arm cover and engine mountings around RM3k+. Be realistic. THP stand for Turbo High Pressure, and it's the pioneer of downsizing + turbo decade ago. You're bound to face this, it's normal. Peugeots and Minis with EP6 Prince engines suffer the same too. Don't compare to a Japanese or naturally aspirated car.

4. The worst of luck is climate control system failure. The cost is from RM2k(cooling coil) to RM15k (evaporator housings and their reduction gears) worst case. I personally do not see this as big issue also because I had same experiences with Mercedes, BMW and Volvo (Yes, don't believe that German cars are bullet proof). One thing I learn though, is never let the climate control work in 'auto' mode. Manually set your temperature and fan speed for all 4 zones. That could prolong the life span.

5. Normal service cost is on par with, if not slightly cheaper than Germans. Key costs include 5.5L of Mobil 1 @ RM70+ per L, brake pads @ RM400+ per pairs, brake disc @ RM500+ per pairs, Naza pricing. I drive my daily fast and hard like a hooligan (yes, I'm not joking), service costs are around RM700+, RM2k+, RM700+, RM2k+...10k km or 3 months interval. Expect lesser for your part if you're a tame driver. I would advise against using Petronas Syntium, the engine feels reluctant to work under Malaysian hot afternoon sun.

6. Maintain your car on strict basis, or even more frequent than what is recommended. THP beefiness and French car hard braking is sweet only when it runs on optimal conditions. You'll hate driving your car if it's not properly maintained. In the event of accident, minor or major, tow back to Sungai Besi Citroen service centre. They do body and painting, and they claimed from insurance.

7. For fuel, RON97 is recommended. RON95 can be used but the engine run very coarse. The difference is very obvious.

(P/S : Sorry for the length. As an owner, I feel sick reading or hearing non owners bashing the marque based on hearsay. Citroens deserve justice.)

Costly? Depends on your financial. Troublesome? Not at all if you can appreciate design and novelty of French cars. High Maintenance? It's roughly the same compare with other newer continentals. The key issue is spare parts availability. And the reason behind key issue is there are too little Citroens on Malaysian road. Junkie? Not at all! If not, how would I keep buying Citroen? It's our third Citroen. And my current ones is even rarer than DS5 or new C4GP.

Long term wise, I would say it's cheaper to have full Naza / Brooklands service record. The cost above is what I personally experienced.

Let's be realistic. How many of us can close eyes and pay RM12k without frawning?

Also, Citroens actually sell very cheap in Malaysia considering what they offer. It's a trap to new buyers too thinking the maintenance is cheap. Smaller Citroens are mechanically simpler and cheaper to maintain like their Peugeot cousins. Big Citroens (Evasion, C4GP, DS5, C6, C8, DS7) are just another story. Don't compare them to Peugeots.

Ok. Engine talk. You can see your engine code on mountings and turbo heat shield.

Marketing terms : THP155 (155hp), THP165 (165hp), THP200 (200hp)
(Note 1 : EP6 engines are underrated on paper. I always get 5~10hp more on dyno run. On wheels, Petron RON100, cooler weather)

Car guy terms : EP6CDT, EP6CDTM, EP6CDTX
(Note 2 : Most Malaysian Citroens are EP6CDT. Newer facelifts EP6CDTM. EP6CDTX on DS4 racing THP200)

Don't worry if you got EP6CDT. Remember the 2 years extended warranty programme? They came with PSA Enhancement programme. Basically you can change new turbo kits, mountings etc, technically updating EP6CDT to EP6CDTM, FOR FREE! That's why I recommend long term wise stick with official service centre. You're banging couple hundreds extras for these ten of thousands juicy parts! Yes, as an owner I'm that calculative! *GRIN* But this shouldn't be new to you if you own Germans, they'll do the same.

Oh, they'll update your ECU mapping too. But I dislike the new one. Less growl, less emission, slightly tamer, greener.

Last note. I think we, as newer Citroen owners should band together for knowledge and defence against common hearsay. Although a lot of Citroen enthusiasts in Malaysia, but majority of them are classic Citroens or Xsara / Xantia era.

Actually I did my enhancement for free, all your mentioned parts, new sensors and more, except mapping and pistons. Finance side Naza claimed from PSA France directly. Lots of strict Terms and conditions applied though. I've been told some Singaporean Cycle and Carriage Citroens also benefitted under the same programme. Seems like a PSA global thingy. I didn't even bought the car from local distributor.

The reason I rejected mapping and pistons because I have different vision for the car. Third party ECU tweak and remain as high compression FI. The quest for 250hp 320Nm. :-)

Too many new turbo cars on the road nowadays. Older cars must update a bit.

The programme is part of 2 years extended warranty. For my case, my service advisor (Last time Glenmarie. Now Puchong branch) informed me right after my 5 years warranty ended.

There is a long list of terms and conditions from PSA for your car to be eligible. One of them is your car must have full service record from official service centre, no skipping no outside workshop. Secondly, your car must be specific year specific VIN code. The rest I can't remember.

What I remember was they gave me a new service booklet. Then PSA guys came to inspect my car, Naza guys just support. On my 80,000km service, they ordered the parts, waited for 3 months, then I left my car for 2 weeks for them to swap everything. Whenever the car has something faulty now, they'll check whether the programme covers free replacement first. So far the most expensive items I replaced was the whole KKK turbo kit (includes down pipe and manifold). Next service I'm going to replace the clutch kit (was told cost around RM4k. Yes, my car is manual).

Hope this helps.

P/S : By the way, Mercedes and BMW have similar programme too. Some of them listed under recall programme. That's why owner of German marques should be familiar with these kind of things.

My daily is a new AP unit bought 6 years ago, I already mentioned I didn't bought my car from local official distributor. And yes, even you didn't buy from official distributor they cannot deny your aftersale service. If you have Xsara, Xantia, Berlingo, Evasion etc, they will service too.

Major ones is ECU and mapping. Minor ones are here and there. EP6CDT is capable of delivering solid power, but very susceptible to heat issue. Your cooling system is the key to first step. Secondly, Aisin 6 speed auto box is just no no. If I'm not mistaken, Citroen sourced their manual box and EGS from Magnetti Marelli. HP isn't difficult, torque is.

But then, I'm more of a Petrolicious guy than an Option guy, so heavily modified cars with big wings and canards here and there are just no no for me. To me, it's a total disrespect for the designers. Now you see why I love Citroen so much, their design is original!

(P/S : Citroen had Donato Coco, the very same designer penned some of the Ferraris and Lotuses.)
