Help differentiating CR/PD

Several Audi, Seat, Skoda and VW model series with 2.0 TDI engines use both CR and PD ("Pumpe-Düse" / Unit injector) technology.

RaceChip chip tuning is specially customised to the applicable fuel injection technology with respect to both hardware and software. If your vehicle is specified in the list of applicable models below (all other 2.0 TDI models feature just one type of technology), it is important to determine, before choosing a tuning product, which type of injection technology is installed in your vehicle. For such models, you will therefore find the “CR” or “PD” designation after your engine code.

Performance The following Volkswagen Group model series are applicable: Engine code CR Engine code PD
100kW (136hp) Audi: A3 (8P), A6 (C6)
VW: Golf Plus, Jetta V, Passat B6
103kW (140hp) Audi: A3 (8P)
Seat: Altea (5P)
Skoda: Octavia (1Z), Superb (3T)
VW: Caddy (2K, 2C), Eos (1F), Golf V,
Golf VI, Jetta V, Passat B6, Touran (1T)

If your vehicle is in this list and you are not sure if it is a CR or PD version, then simply follow one of the following steps to identify CR or PD technology.

Using the engine code:

For PD models, the engine code consists of 3 characters, while for CR there are 4 characters. You can find your vehicle’s engine code in the specification sheet in your service booklet or on the data sticker in your engine bay.

Audi, a strong brand

Even stronger with RaceChip

Audi created the permanent all-wheel drive Quattro, the first German diesel engine with direct injection and turbocharge introduced to the streets. It's also the world's first series saloon constructed with an aluminium integral body.

RaceChip offers performance improvement for almost all Audi models: Whether saloon, coupé or convertible, the Avant, Allroad or Sportback, Roadster or SUV.

Electronic performance improvement for your Audi

You'll experience a whole new level of driving pleasure with RaceChip – that's what an Audi should feel like!

Chip tuning from RaceChip offers you the latest form of electronic performance improvement. A highly sophisticated and individually programmed auxiliary control device is installed between the engine control unit and the sensors – a type of mini-computer with optimisation software developed especially for your Audi engine. This software optimises the electronic signals that control the engine, enabling up to 30% more power (HP) and up to 30% more torque (Nm).

Our way of engine tuning works according to the same principle of electronic performance improvement that Audi itself uses to differentiate models with identical engine blocks. For example, today Audi offers a broad performance range from 150 HP to 190 HP with the same 2.0 TDI basis.

RaceChip performance improvement always stays within your engine's thermal and mechanical power reserves. Your Audi's engine protection system remains completely intact.

Experience your Audi anew: more power, more dynamic, more enjoyment

No matter which Audi you drive, whether a TDI or TFSI, you can experience it in a totally new way with RaceChip chip tuning. Here are just a few of many examples:

For 2.0 TDI engines in the current series (regardless whether in the Audi A3, A4, Q3 or Q5) you can surpass even the next-highest Audi model with RaceChip diesel tuning when it comes to power – and at a much lower price than you would have paid for the more powerful engine from Audi.

The 3.0 TDI (like in the Audi A5, A6, A7 Sportback or A8) shows what it can really do after TDI tuning with RaceChip GTS – with irresistible drive and abundant power. For example, with RaceChip GTS the 218 HP version of the 3.0 TDI with 400 Nm torque can be boosted to 280 HP and an astounding 613 Nm torque.

The A5 Sportback, which comes standard with a 2.0 TFSI engine with 180 HP and 320 Nm torque, undergoes a spectacular transformation with RaceChip RS for 222 HP and 395 Nm: performance data that this premium car can be proud of

From wee to wow – the Audi A1 with the smallest 1.2 TFSI engine (89 HP, 160 Nm) easily bounds over the 100 HP mark with 102 HP (as well as 192 Nm torque) even with our entry-level chip, the RaceChip S.

A Q7 with 4.2 TDI and standard 340 HP comes to life with a RaceChip GTS to feature 393 HP. It shrugs off its heavy SUV side to reveal itself as an agile family vehicle that makes full-throttle acceleration fun. Plus, if you ever want to tow a trailer, then you'll enjoy the higher torque afforded by RaceChip – almost 950 Nm in total.

You can even mobilise power reserves in the absolute top models like the RS6 with RaceChip. The GTS Black catapults these modern 4.0 TFSI turbocharged petrol engines from 560 HP and 700 Nm to over 660 HP and 836 Nm. These values are at least on par with those achieved by prominent Audi tuners like ABT Sportsline. But you get all of this at a much better cost-benefit ratio with RaceChip.
