About the GLA
The GLA is a premium subcompact crossover SUV built and produced by the German automaker, Mercedes-Benz.
Spanning two generations, the GLA was launched in 2013 and is currently the smallest in the lineup of SUVs for Mercedes.
First models were unveiled at the ‘Auto Shanghai’ (an international motor show held once every two years) and had a 2-liter petrol engine coupled with a 7-speed automatic engine with an all-wheel driving system called Mercedes ‘4Matic’ system.
The same year, Mercedes launched the concept vehicle, Concept HLA 45 AMG, a high-performance variant.
First production models began talking orders in November 2013 and were constructed upon the Mercedes-Benz MFA Platform, a platform shared with the S-Class, C-Class, CLS-Class, E-Class, GLC-Class and Mercedes-Maybach S-Class.
2017 saw a new facelift with changes made to the front grille, bumpers and wheels. The original bi-xenon lights were exchanged for LED units and just two years later, the car was given a complete makeover for its second (and latest) generation.
A much taller vehicle, the new GLAs allowed for more space and headroom for rear passengers with the GLA 250 e plug-in hybrid model announced and sold the same year.
Some usual error codes are as follows:
- P0017 – This code can be shown for numerous reasons and relates to the crankshaft position, a mechanic should be consulted.
- P0016 – The crankshaft position on bank 1 is wrong when based on the intake camshaft sensor.
- P0171 – A fault code showing either too little fuel or too much oxygen relating to the fuel system on the first bank of the engine.
- P0420 – A poor catalyst system efficiency. This could mean that oxygen levels are under the required threshold.
- P0172 – Showing there might be too much fuel in the air-fuel mixture.
