  None of the reliability sources we consulted (up!, Mii, Citigo, Fabia III) documents a serious or systemic engine fault. The most frequently cited issues -- an occasional cooling system fault on the Citigo and Mii, and isolated oil consumption on the Citigo -- affect a small minority of the cases analysed.^{[1][3][9][10]}

  On the Seat Ibiza V, the reliability source we consulted documents no serious engine faults; its most cited issue is above-normal oil consumption in a small sample (2 of 5 reviews). There is no published reliability data specific to the Volkswagen Polo VI with this tune.^[2]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

1. 1Medium severityFrequency: OccasionalCoolingCooling system fault with engine light and vibrationsThe 1.0 MPI can suffer a cooling system fault, with the engine light on, vibrations and loss of power. It is documented in a minority of cases on the Škoda Citigo and Seat Mii, and the sources do not describe it as systemic or as linked to other cars with this engine.
2. 2Low severityFrequency: OccasionalLubricationHigher-than-normal oil consumption (most cited on the Seat Ibiza V)The 1.0 MPI can use more oil than normal, especially on the Seat Ibiza V (2 of 5 reviews analysed for the 75 hp version). On the Volkswagen up!, Seat Mii and Škoda Fabia III, with the earlier tune of the same engine, the same pattern is not documented in a comparable proportion.
3. 3Low severityFrequency: RareTimingTiming belt with no fixed replacement intervalThe 1.0 MPI uses a dry timing belt which, according to the manufacturer, has no fixed replacement interval: it only calls for a visual inspection from 210,000-240,000 km. The sources we consulted document no failure pattern for this belt on any car with this engine.
4. 4Low severityFrequency: RareElectronicsOccasional sensor or throttle body faults (isolated cases)The Škoda Fabia III with the 1.0 MPI records an isolated case of throttle body failure (at 80,000 km) or lambda sensor failure. These are one-off cases, with no pattern, within a sample the sources describe as mechanically stable.

Technical data^[5][6][7][8]

1. 2011–2023

   1.0 MPI 60/75 (CHYA/CHYB, 2011-2023)

   Original tune of the engine, launched in 2011 with the Volkswagen up!, Seat Mii and Škoda Citigo in two outputs (60 and 75 hp, the same block with different programming). It spread, with no design changes noted in the sources, to the Volkswagen Polo V (April 2014 facelift) and the Škoda Fabia III (from its launch in October 2014), which kept it until the end of that generation.^{[5][6][7][11][12]}

2. since 2017

   1.0 MPI 65/75 (CHYC/CPGA, 2017-)

   Tune introduced in 2017 with the new MQB-A0 platform of the Volkswagen Polo VI (65 hp, code CHYC documented from September 2017) and the Seat Ibiza V (75 hp variant). The EA211 family code CPGA (50 kW / 68 hp) probably replaced CHYC after WLTP rules came into force in 2018, although the sources we consulted do not explicitly confirm this for a specific car and date.^[2][5][8]
