Common Failure
The OM654 is generally reliable, but EGR cooler thermal cracking is a documented issue - coolant loss without visible external leakage is a key symptom. AdBlue system crystallisation and turbocharger issues from contaminated crankcase ventilation have also been reported.
The Mercedes Benz GLA 200 d and 220 d rely on the OM654 2.0-litre modular diesel - a lightweight, all-aluminium engine praised for refinement and efficiency, but not without its vulnerabilities. EGR cooler thermal cracking, AdBlue system failures, and turbocharger issues dominate replacement demand, particularly on post-2020 H247 models. Every rebuilt engine supplied through EnginesMarket includes upgraded components designed to address the original failure point - plus a minimum 12-month unlimited mileage warranty. Below we break down the most common GLA 200 d and 220 d engine failures, what they cost to fix, and when replacement is the smarter financial decision.
Why the GLA 200 d / 220 d Loses Coolant
Affected Vehicles
Mercedes Benz GLA Class GLA 200 d, GLA 220 d (OM654.920, 2020-present)
Typical Failure Mileage
40,000 - 70,000 miles
Root Cause
The OM654's exhaust gas recirculation (EGR) cooler is subject to thermal cycling between exhaust gas temperatures and coolant. Differential expansion causes microscopic cracks in the cooler matrix, allowing coolant to be drawn into the intake manifold. The result is progressive coolant loss, white exhaust smoke, and eventually hydrolock if ignored.

Vehicle Value Check
Vehicle Value Check
A typical H247 GLA 200 d or 220 d is worth £18,000-£35,000 depending on age, mileage and condition - the full replacement cost of £2,800-£5,500 is modest relative to vehicle value, making a specialist rebuilt engine a sound investment. For vehicles worth under £15,000, evaluate repair options first.
Our Recommendation
Our Recommendation
On a newer GLA 200 d or 220 d, the EGR cooler replacement at a specialist (£600-£950) is a no-brainer. However, if your car has already overheated or shown misfire symptoms, pay for a borescope inspection before committing to repairs - bent rods are not always immediately obvious. Rebuilt OM654 units with upgraded EGR systems are increasingly common as these cars age out of manufacturer warranty.
Don't Let Engine Failure Write Off Your Mercedes Benz GLA 200 d or GLA 220 d

Mercedes Benz GLA Class 200 d / 220 d Engine ReplacementFrequently Asked Questions
Question 1How much does it cost to replace a GLA 200 d or GLA 220 d engine in the UK-
A GLA 200 d or GLA 220 d engine replacement typically costs between £2,500 and £6,000 depending on condition type and whether fitting is included. OM654 2.0-litre diesel units range from £2,500 to £6,000 supply only.
- Rebuilt OM654 (GLA 200 d / 220 d): £2,500-£6,000 supply only
- Reconditioned units: £3,200-£5,000
- Used engines from breakers: £1,800-£3,500 but higher risk
- Labour for supply & fit adds £800-£1,500 to any engine price
Question 2Is the OM654 engine in the GLA 200 d and 220 d reliable-
The OM654 is a highly refined and efficient engine, praised for its lightweight all-aluminium construction and reduced friction losses. However, it has several well-documented issues that owners should be aware of.
- EGR cooler thermal cracking causing coolant loss
- AdBlue system crystallisation on urban-driven vehicles
- Timing chain and injector issues on higher-mileage units
- With regular maintenance and long journeys, 150,000+ miles is realistic
Question 3What are the signs of OM654 EGR cooler failure in a GLA diesel-
The OM654's EGR cooler typically fails between 40,000-70,000 miles, with several warning signs.
- Coolant level dropping with no visible external leak
- White smoke from the exhaust
- Check engine light illuminated
- Decrease in engine performance and rough idle
- Increased fuel consumption
Question 4Should I repair or replace my GLA 200 d or 220 d engine-
Repair if the failure is isolated (e.g., EGR cooler, AdBlue dosing module, injectors). Replace if there's bottom end damage, bore scoring, or catastrophic timing chain failure.
- EGR cooler replacement at specialist: £600-£950 - excellent value if caught early
- AdBlue dosing module replacement: £500-£800 - sensible repair for urban-driven cars
- Full OM654 rebuild: £2,800-£5,500 - for catastrophic failure or 100k+ miles
- Given GLA 200 d / 220 d values (£18,000-£35,000), a rebuilt engine is typically good value
Question 5How do I know which engine code my GLA 200 d or 220 d has-
Check your vehicle log book (V5C) for the engine number, which includes the engine code prefix.
- V5C log book shows full engine number with code prefix
- Engine code stamped on cylinder block
- GLA 200 d (2020-present): OM654.920 (2.0L diesel, 150hp)
- GLA 220 d (2020-present): OM654.920 (2.0L diesel, 190hp)
- Service history documents list engine type
Question 6Can I fit a used GLA 200 d or 220 d engine myself-
We strongly advise against DIY fitting on a GLA diesel. The complex emissions systems, 8G-DCT gearbox alignment, and ECU coding requirements demand specialist equipment and expertise.
- 8G-DCT transmission alignment requires specialist knowledge
- AdBlue and SCR system calibration needed
- ECU coding and immobiliser synchronisation required
- Specialist supply & fit costs £800-£1,500 - worth every penny
Question 7What warranty comes with a reconditioned GLA 200 d or 220 d engine-
Every engine supplied through EnginesMarket carries a minimum 12-month unlimited mileage warranty, with many specialists offering 24-month coverage on OM654 rebuilds. This includes parts and labour for any manufacturing defect or installation error.
- 12-month unlimited mileage is the minimum standard
- OM654 rebuilds often include 24-month warranty
- All warranties cover parts, labour, and MOT compliance
- Extended warranties available at point of purchase
